Problem placing and deleting elements from select to an html textarea

  • 772

I want to place the elements of a select to a textarea, the code I have works well to add the text, but the problem arises when I delete the text from the textarea, if I delete something from it, it does not let me put more text back from the select, then I put the code I have.

function agregar(texto){
  console.log(texto);
  $("#test1").append(texto+"\n");
}
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <script src="https://code.jquery.com/jquery-3.1.0.js"></script>
  <title>Problema</title>
</head>
<body>
<select name="" id="test" onchange="agregar($('#test option:selected').text())">
  <option value="1">Uno</option>
  <option value="2">Dos</option>
  <option value="3">Tres</option>
  <option value="4">Cuatro</option>
</select>
  <br/>
<textarea name="" id="test1" cols="30" rows="10"></textarea>
</body>
</html>

How could I solve this problem, or why is this?

    Well, I would solve it in the following way:

    textareait is a text input element for which it would not capture its value with , .html()but with .val()and likewise it would be assigned since it is really the function that corresponds to it, here is an example:

    function agregar(texto){
  var html = $("#test1").val();
  html += texto + "\n";

  $("#test1").val(html);
}
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="" id="test" onchange="agregar($('#test option:selected').text())">
  <option value="1">Uno</option>
  <option value="2">Dos</option>
  <option value="3">Tres</option>
  <option value="4">Cuatro</option>
</select>
  <br/>
<textarea name="" id="test1" cols="30" rows="10"></textarea>
